Abstract: A workholding device for positioning a workpiece on a machining equipment, comprising a sacrificial support for supporting the workpiece, a workpiece holding layer formed of a curable material applied onto the sacrificial support, a curable material collector, a curing processing unit which comprises a controller and a curing rate regulator, and a bearing assembly for supporting the sacrificial support, the curable material collector and the curing processing unit, wherein the curable material is a solid which is viscous before curing and elastic after curing and has a melting point above 1000° C.

Abstract: The present invention relates to a workholding device and method, and specifically provides a workholding device for positioning a workpiece on a machining equipment, which comprises: a sacrificial tray for supporting the workpiece; a workholding layer formed of a curable material applied on the sacrificial tray, which secures the workpiece at a predetermined position on the sacrificial tray upon completion of the curing, wherein the sacrificial tray and the workholding layer are allowed to be damaged by a cutting head of the machining equipment during machining of the workpiece; a curable material collector arranged below the sacrificial tray to collect the curable material that detaches from the sacrificial tray during the application of the curable material, the curing of the curable material, and/or the machining of the workpiece; a curing processing unit comprising a controller and a curing rate regulator, wherein the controller controls the curing rate regulator to regulate curing rate of the curable ma

Abstract: The present invention provides a multiple sensors-based flexible anti-theft system, and a security travel bag and an anti-sexual assault garment using flexible anti-theft system. The flexible anti-theft system will not falsely trigger an alarm due to the overall motion or acceleration changes of a transport vehicle, and can effectively prevent personal articles in a suitcase or bag from theft. The flexible anti-theft system comprises: a multi-sensor module configured to correspondingly attach multiple motion sensors to multiple positions of the flexible material; a microprocessor module configured to receive output information from the multiple motion sensors and deduce, according to the output information, whether the flexible material undergoes abnormal movement; an alarm module configured to send out an alarm according to a judgment result of the microprocessor module; and a user identity authentication and working mode switching module connected with the microprocessor module.

Abstract: Monomers and polymers useful for forming photoresists are provided. More particularly, photoresists, as well as monomers and polymers for photoresists useful in micro-lithography, specifically monomers bearing acid-labile groups of reduced optical density. The resulting photoresists exhibit improved transparency to 157 nm light. The photoresist compositions are composed of a mixture of at least one water insoluble, acid decomposable polymer which is prepared from at least one monomeric unit which comprises an acid labile group of the formula —OC(CH3)2CF3 and which is substantially transparent to ultraviolet radiation at a wavelength of about 157 nm and at least one photoacid generator capable of generating an acid upon exposure to sufficient activating energy at a wavelength of about 157 nm.

Abstract: A rolling toy includes a chassis, an electric power source attached to the chassis, a remote signal receiver, an electric motor attached to the chassis and receiving power from the power source in response to a signal received by the remote signal receiver, a pair of riding surface-engaging wheels mounted co-axially to the chassis and capable of rotating independently of one another, and wherein at least one of the wheels is driven to rotate by the electric motor, and a dome-shaped profile formed on each wheel and adapted to bear upon the riding surface to assist in righting the toy, should it topple in use.
